The investment value will be $465.15.The amount he invested will be $200.

<h3>What is compound interest?</h3>

Compound interest is computed on a loan or deposit based on the starting principle and the preceding period's accrued interest.

Money invest one time in six months = $20

Interest = 17%

Compounded type = semi-annually

The principal amount invested:

Money invested = $ 20 in 6 month

If he invests for 5 years, in 5 years there are 10 times she invests;

Investment(principal)=$ 20 × 10

Investment(principal)=$ 200

The compound interest:

$A= 200(1+\frac{0.17}{2})^2.5 \\\\ A=$ \ 452.2$

A =P+CI

452.2=200+CI

CI=252.2

The final balance is $452.2.

The total compound interest is $252.2.

Hence, the investment value will be $452.2.

Suppose the number of corn kernels on an ear of corn is normally distributed. For a random sample of ears of corn, the confidenc

Dafna11 [192]

Answer:

The error bound is of 13.5 corn kernels.

Step-by-step explanation:

Any confidence interval has a lower bound and an upper bound. The error bound is the difference between the values of those two bounds, divided by 2.

In this problem, we have that:

Lower bound: 858.50

Upper bound: 885.50

Error bound: (885.50-858.50)/2 = 13.5

The error bound is of 13.5 corn kernels.

A line passes through the point (3 comma 1 comma negative 8 ), and is parallel to the vector 5 Bold i plus 3 Bold j plus 3 Bold

motikmotik

The line $\ell$ passing through (3, 1, -8) and running parallel to the vector <5, 3, 3> has the vector equation

$\ell=(3\,\vec\imath+\vec\jmath-8\,\vec k)+t(5\,\vec\imath+3\,\vec\jmath+3\,\vec k)$

$\ell=(3+5t)\,\vec\imath+(1+3t)\,\vec\jmath+(3t-8)\,\vec k$

and from this we can extract a set of parametric equations for the line:

$\begin{cases}x(t)=5t+3\\y(t)=3t+1\\z(t)=3t-8\end{cases}$

where $t\in\Bbb R$ .

Calculate the area of a circle with a radius of 2 cm and a circle with a radius of 4 cm. leave your answers in terms of pi. when

Korolek [52]

Area of the circle with radius 2:
A = pi * radius^2
= pi * 2^2
= pi *4
= 4pi cm^2
Area of the circle with radius 4:
A = pi * 4^2
= pi * 16
= 16pi cm^2

16 is not 4*2 so no the statement is incorrect
B is the correct option
